Aha.  Well, I'm glad you figured out the problem.

Yes, various things have been tried.  The top-level Makefile and
bsd.*.mk files are more of an art than a science.  The current scheme
was a big step forward from what we had before.  It made it possible
to build -current on a -stable system, for instance.  But I don't
think anybody would argue that it's perfect.
